Subject Java: Write an application that will assist the user with metric conversions. Your application should allow the user to specify the names of the unitys as strings( i.e.centimeters, liters,grams, and so on, for the metric system and inches, quarts, pounds, and so on, for the english system) and should respond to questions such as

"How many inches in 2 meters?"

"How many liters are in 10 quarts?"

Your application should recognize invalid conversions. For example the question

"How many feet are in kilograms?"

I was wondering if anyone had done this program before and would have an example I could base my program on or some guidance on how I should start it.Thank you!
